Dear Mybat, I wish a Refuah Shlema to your acquaintance.
He is one of the winners (or losers) in the flu vaccine lottery, I suppose. He is suffering because thousands of others have been saved from suffering, but he is truly is unfortunate. Chances are he would not have gotten Guillain-Barre’ syndrome w/o the flu shot.
But, 999,999 other people got the vaccine, and at least 1000 of them will avoid death, and many will avoid suffering. Prayers for his health should peppered with prayers of gratitude.
Thanks heavens that Hashem gave us a big brain so that some of us could understand some of the universe he created so well that we are able to alleviate so much human suffering in our world.
Please bless and keep the public health workers, the scientists, the doctors and the nurses who have devoted themselves to partnering with Hashem to make life in this world healthier and better.
